Abstract

The invention provides a lifting and rotating device and method for adjusting balance. The device comprises a sliding clamping head (1), a rotary supporting rod (2), a guide supporting rod (3), a lifting guide support (4), an adjustable counterweight (5), a worm and gear speed reducer (6), an actuating cylinder (7), a bearing (8) and a rail (10); the actuating cylinder (7) is connected with the guide supporting rod (3) and used for driving the guide supporting rod (3) to ascend and descend; a through hole is formed in the guide supporting rod (3), a bearing (8) is arranged in the through hole,and the rotary supporting rod (2) penetrates through the bearing (8) and is perpendicular to the guide supporting rod (3); and the first end of the rotary supporting rod (2) is connected with the sliding clamping head (1), the sliding clamping head (1) is used for clamping a paddle, and the second end of the rotary supporting rod (2) is connected with the adjustable counterweight (5). The bladesare convenient to clamp and rapid to position, the mounting and detecting efficiency of the blades can be effectively improved, the labor intensity is reduced, and the clamping, detecting and positioning requirements of batch production are met.

Description

technical field [0001] The invention belongs to the field of tooling design, and in particular relates to a lifting and rotating device and method for adjusting balance. Background technique [0002] The composite rotor blade is an important moving part of the helicopter, and it is necessary to measure the comprehensive angle, weight, center of gravity, static moment, etc. of the composite rotor blade. [0003] However, the composite material rotor blade is a slender and complex piece with weak stiffness, which will be bent downward due to the weak stiffness of the blade, and the length of the blade far exceeds the size of the clamping platform. When measuring the rotor blade There are great difficulties in attitude rotation transformation. Contents of the invention [0004] The invention provides a lifting and rotating device and method for adjusting balance, which solves the problem of rapid change of measuring attitude of the existing blades. [0005] The invention pr...
